Flare union bodies create a removable, leak-resistant connection between two flare-end tubing runs without requiring solder or brazing. This type of fitting is commonly found in refrigeration, HVAC, and gas piping systems where technicians need a mechanical joint that can be broken and remade during service. Licensed HVAC technicians and refrigeration mechanics are the primary installers of this hardware.\u003c\/p\u003e\u003cp\u003eThe 42R-84 is suited for applications requiring a transition or union between 1\/2 inch and 1\/4 inch flare connections. Typical use cases include connecting refrigerant line sections, instrument tubing, or gas supply lines in both residential and light commercial systems. The asymmetric port sizing makes it appropriate for reducing or step-down union connections within a flare-type piping arrangement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDual-size flare ports: 1\/2 inch on one end, 1\/4 inch on the other\u003c\/li\u003e\n\u003cli\u003eUnion-style body allows the joint to be disconnected and reconnected without cutting tubing\u003c\/li\u003e\n\u003cli\u003eFlare-type connection eliminates the need for solder or open flame during assembly\u003c\/li\u003e\n\u003cli\u003eCompact body design suited for tight equipment enclosures\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service fitting for HVAC, refrigeration, and gas piping systems using standard flare-type tubing connections in 1\/2 inch and 1\/4 inch sizes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis fitting is typically installed by licensed HVAC technicians or refrigeration mechanics. Before servicing any refrigerant circuit, recover refrigerant in accordance with EPA Section 608 regulations and relieve system pressure. Ensure tubing ends are properly flared using a calibrated flaring tool before tightening flare nuts to the union body. Do not overtighten flare connections, as this can crack the flare seat and cause leaks.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1\/2 inch x 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Flare union\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HOLYOKE FITTINGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 42R-84\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLYOKE FITTINGS","offers":[{"title":"Default Title","offer_id":51383523148082,"sku":"42R-84","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/42R-84.jpg?v=1782599339","url":"https:\/\/voomisupply.com\/products\/holyoke-fittings-42r-84-flare-union-body-1-2-x-1-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
